artransform: Mapping real valued parameters to stationary region
Description
Function artransform transforms \(p\) real valued parameters to
stationary region of \(p\)th order autoregressive process using
parametrization suggested by Jones (1980). Fortran code is a converted from
stats package's C-function partrans.
Usage
artransform(param)
Value
transformed The parameters satisfying the stationary constrains.
Arguments
param
Real valued parameters for the transformation.
